3-(4-iodophenyl)bicyclo[1.1.1]pentane, prepared in 63 % yield by iodination of 1,3-diphenylbicyclo[1.1.1]pentane, was selectively mono-coupled with 9-ethynyl-1,5-dimethoxy-10-phenylethynylanthracene (26), and subsequently with the zinc derivatives of 1-(2-methyl/methoxy-4-methyl-5-phenylthiophen-3-yl)-2-(2-methyl/methoxy-4-methylt hiophen-3-yl)perfluorocyclopentenes (38-H-41-H). Regioselective synthesis of the
Novel 9-substituted or unsubstituted thienyl-3,7-dimethyl-nona-2,4,6,8-tetraene derivatives, useful as antitumor agents as well as processes for their preparation and novel intermediates are disclosed.
Two types of diarylethene, each of which contains a naphthalene and a thiophenering, were synthesized, and their photochromicproperties were studied. The photochromicproperties are dependent on the bridge position of the thiophenering. The cycloreversion of one of the closed forms of some of the diarylethenes occurred almost photon quantitatively, and the photochromic reactions were thermally irreversible
